Hi Hans,
How to pass the "SomeText" parameter ?

\setupbodyfont[pagella,11pt]

\setupcolors[state=start]

\defineframedtext
  [SomeText]
  [before={\blank},
   after={\blank},
   frame=off,
   background=MyFrame,
   width=\textwidth,
   height=fit,
   style=italic]

\startuseMPgraphic{MyFrame}
 path b;
 picture p;
 p := textext.rt("\white SomeText");
 p := p shifted (2BodyFontSize,OverlayHeight-ypart center p+.25ExHeight);
 b := boundingbox p leftenlarged .5EmWidth rightenlarged .5EmWidth;
 fill OverlayBox withcolor lightgray;
 fill b withcolor darkred;
 draw bottomboundary OverlayBox withpen pencircle scaled 1pt  withcolor
darkred;
 draw topboundary OverlayBox withpen pencircle scaled 1pt  withcolor
darkred;
 draw p;
 setbounds currentpicture to boundingbox currentpicture enlarged 2mm;
\stopuseMPgraphic

\defineoverlay
  [MyFrame]
  [\useMPgraphic{MyFrame}]

\starttext

\startSomeText{SomeText1}
\input knuth
\stopSomeText

\startSomeText{SomeText2}
\input knuth
\stopSomeText

\stoptext

Thanks
Fabrice
